I have a very simple setup, 2 vLANS, with inter-vlan routing enabled and working perfectly (machines on either vlan can ping one another). I need to use a second external IP to send traffic to vLAN 2. The moment I enable the One to One NAT checkbox I am unable to ping from vLAN 2 to vLAN1. I am still able to ping from vLAN 1 to vLAN 2 however.
I have tried inserting access rules into the firewall that allow all traffic from vLAN 1 to 2 and vice versa... but with no success.
This can't be an unusual configuration request. What am I doing wrong?
